Milk is a valuable resource which unlocks the Kitten series of upgrades that greatly increase cookie output rate in direct correlation to the amount of Milk the player has. Milk is gained by unlocking normal (non-Shadow) Achievements at a rate of 4% milk per Achievement. As of version 2.021, the total number of normal achievements that count towards milk is 439 and the maximum attainable Milk amount is 1,756%.
The Milk is represented by a wave-animated overlay at the bottom of the Big Cookie partition. The overlay gradually gains height as the Milk percentage increases. The milk changes color and name when the Milk percentage reaches a new hundred, although this has no effect on cookie production. New Milk types and Kitten Upgrades have been introduced with new Achievements and the consequential higher possible Milk levels.
AppearanceEdit
As the player gains more and more (non-shadow) achievements, Milk will change its appearance and flavor. The current Milk flavor and rank is shown at the top of the Achievements section in Stats.
After purchasing the Classic dairy selection heavenly upgrade, you may freely choose the flavor of Milk using the "Milk selector" switch. However, this is only a cosmetic change, and does not affect the information shown in the stats menu. Additionally, there are 9 more types of Milk added by purchasing the Fanciful dairy selection heavenly upgrade: Zebra Milk, Cosmic Milk, Flaming Milk, Sanguine Milk, Midas Milk, Midnight Milk, Green Inferno Milk, Frostfire Milk and Soy Milk. These new types of Milk are unique in introducing not only new colors, but new patterns to the Milk.

KittensEdit
There are 13 regular kitten upgrades, a kitten-like fortune upgrade, and a heavenly upgrade sharing the same type of milk-based effect.

Each kitten upgrade's milk factor, multiplied by the milk percentage, provides a CpS production boost. These effects stack multiplicatively. For example, say you have Kitten helpers, Kitten engineers, and 160% Milk (40 achievements). Kitten helpers multiplies production by 1 + 1.6 * 0.1 = 1.16, and Kitten engineers multiplies production by 1 + 1.6 * 0.15 = 1.24. Combined, these two multipliers will get you a total production multiplier of 1.16 * 1.24 = 1.4384. You can check the overall Kitten multiplier in top of Achievements section in Stats.
ModifiersEdit
There are modifiers that can increase the milk percentage before the kitten upgrades are calculated.
Modifier | Milk Multiplier |
---|---|
Santa upgrade: Santa's milk and cookies | 1.05 |
Auras: Reality Bending / Breath of Milk / Both | 1.005 / 1.05 / 1.055 |
Mokalsium, Mother Spirit: Diamond / Ruby / Jade | 1.1 / 1.05 / 1.03 |
Garden plants (mature, clay) | 1+0.0025W W = # of Whiskerbloom |
These are multipliers to the Milk percentage and stack with each other multiplicatively. For example, if you have 160% milk, the effective milk% will be 160% * 1.05 = 168% with one of the 1.05 modifiers (Santa upgrade, Breath of Milk aura, or Mokalsium in the ruby slot). With three 1.05 modifiers, the effective milk will be 160% * 1.05^3 = 185.22%.
Total Modifier | Without Santa's Milk and Cookies | With Santa's Milk and Cookies | ||||||
---|---|---|---|---|---|---|---|---|
Mokalsium: | N/A | Jade | Ruby | Diamond | N/A | Jade | Ruby | Diamond |
No Dragon Aura | 1 | 1.03 | 1.05 | 1.1 | 1.05 | 1.0815 | 1.1025 | 1.155 |
Reality Bending | 1.005 | 1.03515 | 1.05525 | 1.1055 | 1.05525 | 1.0869075 | 1.1080125 | 1.160775 |
Breath of Milk | 1.05 | 1.0815 | 1.1025 | 1.155 | 1.1025 | 1.135575 | 1.157625 | 1.21275 |
Both Auras | 1.055 | 1.08665 | 1.10775 | 1.1605 | 1.10775 | 1.1409825 | 1.1631375 | 1.218525 |
The effect of Garden plants on Milk percentage is much more complex. The power of Whiskerbloom can be increased by Nursetulip, but Nursetulip itself will reduce overall CpS. See the following examples for detailed discussion. All examples assume:
- All 439 achievements obtained, 1756% base milk% (maximum as v2.021)
- All kittens owned (including Fortune #103)
- All 3 non-garden modifiers owned
- Aura: Breath of Milk only
- Mokalsium: Diamond slot
- All plants are mature
- The soil is clay.
Example 1Edit
A full 6x6 plot of 36 Whiskerblooms has the modifier, f_{W}, of 1 + 0.0025 * 36 = 1.09, and combining all other three non-garden multipliers will give the effective milk percentage:
$ M=1756%*1.05*1.05*1.1*f_W = 2321.25201% $
The resulting Kitten multiplier will then be:
$ K_1=(1+0.05M)(1+0.1M)^2(1+0.115M)(1+0.125M)^2 $
$ K=K_1*(1+0.15M)^2(1+0.175M)^2(1+0.2M)^5 $
Which is approximately 3,919,378,731.
Example 2Edit
To reach the highest possible effective milk percentage, the Garden should be planted as follows:
W: Whiskerbloom, n: Nursetulip | |||||
W | W | W | W | W | W |
n | n | n | n | n | n |
W | W | W | W | W | W |
n | n | n | n | n | n |
W | W | W | W | W | W |
n | n | n | n | n | n |
Each Nursetulip (in clay) boosts adjacent plants' effects by 5/4
The overall Whiskerbloom modifier will be:
$ f_W=1+\frac{1}{400}\left[2\left(\frac{5}{4}\right)^2+4\left(\frac{5}{4}\right)^3+4\left(\frac{5}{4}\right)^4+8\left(\frac{5}{4}\right)^6\right]=\frac{9241}{8192} $
The max effective milk percentage which can be achieved is:
$ M=1756%*1.05*1.05*1.1*f_W\approx 2402.2866% $
The resulting Kitten multiplier would be:
$ K_1=(1+0.05M)(1+0.1M)^2(1+0.115M)(1+0.125M)^2 $
$ K=K_1*(1+0.15M)^2(1+0.175M)^2(1+0.2M)^5 $
This is approximately 5,809,133,949.
However, single Nursetulips in clay also reduce overall CpS by 1/40.
In this arrangement, they reduce CpS by a factor of:
$ f_N=\left(1-\frac{1}{40}\frac{5}{4}\right)^6\left[1-\frac{1}{40}\left(\frac{5}{4}\right)^2\right]^{12}=\left(\frac{31}{32}\right)^6\left(\frac{123}{128}\right)^{12}\approx 0.5124033903 $
Which means the overall production multiplier is only f_{N} * K ~ 2,976,619,930. Thus, despite having the largest possible Kitten multiplier, this setup is far less efficient due to the Nursetulip factor.
Example 3Edit
To offset the Nursetulip debuff, the best garden arrangement is:
W: Whiskerbloom, n: Nursetulip | |||||
W | W | W | W | W | W |
W | W | W | W | W | W |
W | W | n | W | n | W |
W | W | W | W | W | W |
W | W | n | W | n | W |
W | W | W | W | W | W |
The total Whiskerbloom modifier for this setup is:
$ f_W=1+\frac{1}{400}\left[11+12\frac{5}{4}+8\left(\frac{5}{4}\right)^2+\left(\frac{5}{4}\right)^4\right]=\frac{112881}{102400} $
The effective milk percentage for this setup is:
$ M=1756%*1.05*1.05*1.1*f_W\approx 2347.5599% $
Which gives the Kitten multiplier:
$ K_1=(1+0.05M)(1+0.1M)^2(1+0.115M)(1+0.125M)^2 $
$ K=K_1*(1+0.15M)^2(1+0.175M)^2(1+0.2M)^5 $
This is approximately 4,458,570,563.
The Nursetulip factor will be:
$ f_N=\left(1-\frac{1}{40}\right)^4=\left(\frac{39}{40}\right)^4\approx 0.9037 $
With a resulting overall production multiplier of f_{N} * K ~ 4,029,156,227, which is ~1.3536 times as much as the previous example, and 2.8% higher than the simple arrangement of 36 Whiskerblooms.
GraphsEdit
The top image shows the multipliers for each kitten upgrade, based on the milk percentage. In each group of 3 lines, the bottom line is the base multiplier, the middle line is the multiplier with either Santa's milk and cookies or Breath of Milk, and the top line is the multiplier with both. In the endgame, each of the last 4 kitten upgrades triples production.
The bottom image shows the multiplier for the Breath of Milk dragon aura, based on the milk percentage and which kitten upgrades are active. In each group of 4 lines, grouped by color, the bottom line is the base multiplier, the next line is the multiplier with Santa's milk and cookies, the next line is the multiplier with Kitten angels, and the top line is the multiplier with both. The lines for each kitten upgrade assume that all previous kitten upgrades are active as well. Also, since Breath of Milk and Santa's milk and cookies have identical effects, their meanings on the chart can be swapped.
Dunking the CookieEdit
The Cookie-dunker Achievement is gained by accumulating enough Milk and adjusting the browser window in a way that the Big Cookie is overlaid by the Milk graphic on a sizeable area. This can be done by zooming in a lot or reducing the height of the page for instance, pressing F12.
